To all whom it may concern:

Be it known that I, IVNLTER PRQULX, a citizen of the United States, residing at Lewiston, county of Androscoggin, State of Maine, have invented certain new and useful Improvements in Pulling-Over Machines, of which the following is a specification.

This invention relates to pulling over machines and particularly to pulling over machines for turn shoe manufactures.

One of the problems which has always been present sincethe adoption of the pulling-over machine for turn shoes is the 'mat ter of accurately gaging the tip of each pair of shoes before the stock 1s lasted and stitched, for unless the tips are accurately gaged the shoes will be mismated. In the manufacture of turned tip shoes, as heretofore practised with the pulling over machine, the stock and lining are temporarily tacked to the last by separate tacking operations, in order that the shoe tip may be gaged before the lining is laid over it and tacked in position; that is, the upper is placed on the last in position with the lining thrown back in order to eXpose the tip for gaging, after which the upper is tacked to the last by driving a row of tacks around the toe and sides. The lining is then draw-n over the lasted upper and tacked by driving a second row of tacks. Where it has been attempted to tack the stock and lining simultaneously, the tip has generally been improperly set, because it was covered by the lining and could not therefore be seen by the operator. The two separate tacking operations are therefore generally performed, and although the speed of the machine is slowed up to that extent, are preferable as against any method which makes for mismated shoes due to inaccurate gaging of tips.

When the lining is separately tacked over the stock, however, it completely cove-rs the first row of tacks which were driven to fasten the stock to the sole, so that these tacks are concealed by the lining and are therefore difficult to find when the tack-puller is ready to draw them out, after the upper has been run through the stitch-in machine. Thus it frequently happens that fiiese tacks are not drawn, and the shoe goes to the trade with tacks left in it. Moreover the tacks, being concealed by the lining, are not seen by the stitcher who frequently runs into them, breaking the needle of the stitching machine;

The object of my invention is to provide a anethod of and apparatus for pulling over and temporarily attaching the stock and lining to the shoe which will overcome these several objections. According to my invention, I last the stock and lining to the sole, by machine, in a single tacking operation but in such a way as to leave all tacks ex posed, and provide, moreover, for the proper gagmg of the tip before the tacks are driven. This method not only avoids the objections to the present methods, but saves time and requires the driving of only nine tacks in a sing le'tackingoperation as compared with the fourteen tacks now required to be driven by two separate and distinct tacking operations.

In carrying out my invention, the upper of a turned shoe is first laid over the last without tacking and with the lining thrown back to expose the tip marking of the upper, the tip gaged, and the lining laid over the upper and engaged by a jaw independent of the upper clamping jaw, whereupon the usual wiper oft-he machine tucks in the upper and lining at the toe, and the lining is drawn taut, after which the driving bar's operate to set a single row of nine tacks through both the lining and stock. The shoe is now lasted and is passed on to the side-laster who sets the tacks around the shank and heel, and passes the shoe to the sti-tcher, from whom it goes to the tackpuller, and afterward to the turner.

invention in its simplest form may be ei'n-bodied as an attachment for the usual pulling-over machine now on the market, and in the accompanying drawings I have il lustrated it as applied to the well-known Rex pulling-over machine, in which application it involves but slight modification of structure.

The nature and manner of practising my method, together with a preferred form of apparatus for carrying out the principles involved, is fully described in the following specification and illustrated in the accompaiaying drawings, and the parts, improvements and combinations which I claim as my invention are particularly pointed out and distinctly claimed in the appended claims.

Throughout the specification and drawings', like reference characters are correspondingly employed, and in the drawings,

Figs. 10, 11 and 12 are views similar to Fig. 9 and illustrating th successive operations of inserting the stock, clamping the v stock and inserting the lining, respectively.

My method, and the apparatus for practising it, may be conveniently embodied in the familiar pulling over machine now upon the market, with but slight modifications of existing structure, and I have so shown it in these drawings.

I have indicated at l a last upon which are first assembled the upper materials of a turn shoe, including the upper U, the toe cap marking of which is indicated by the dotted lines, Fig. 3, at 2, and the lining L, as Well as the usual toe stiifeners, and the inner sole, whereupon the shoe is then presented, bottom-uppermost, against a heel rest 3, extending from the head of the pulling-over machine, so as to dispose the projecting edges of the upper within the influence of the usual side and to grippers G, being held in this position by suitable clamps C.

The grippers G are substantially alike in operation and construction and one is illustrated in detail, Figs. 7 to 12, inclusive, and described in detail hereinafter. Referring to these figures, the gripper is formed as a suitable bar adapted to be connected at its inner end with actuating mechanism for moving it, of which mechanism only the lev'er 154 is shown, and supporting at its outer end three superposed gripping jaws 4, 5 and 6, of which the lowermost jaw 4 is a fixed jaw and the intermediate and upper jaws are pivoted jaws, all jaws having their coactive faces serrated as shown to assist gripping action, and the gripper bar supporting means for opening and closing the jaw 5, of which means only the usual spring-com trolled slide 86 and latch 88 are shown.

The upper U is adapted to be inserted between the fixed 4 and the intermediate pivoted jaw 5 (Fi 10), and after the toe cap has been gagec, by means of the indicated marking 2 (Fig. 3), the jaw 5 is closed down upon the gaged stock (Fig. 11), by the actuation of the slide 86 to rock said jaw on its pivot 5 and clamp the stock in position for lasting. Under these condltions, it is possible to secure accuracy of gaging, for the lining L is thrown back to expose the tip marking 2.

The lining L is next inserted between the pivoted intermediate jaw 5 and the upper jaw 6, Fig. 12, whereupon, the upper jaw 6 is rocked on its pivot 6 to clamp the lining against the cooperating face of the intermediate jaw 5, Fig. 9. The mechanism for closing the jaw 6 is independent of that for operating the jaw 5, and as here shown may conveniently consist of a pivoted, spring tensioned latch piece 62, to which at 63 one end of a relatively stiff coil spring 64 is attached, the other end of said spring being anchored at 65 to the outer end of the driver bar. When the latch is in its normal latched position in which the pin 63 is seated on a lockino shoulder 66 formed 011 the latch piece T, Fig. 10, the jaw 6 is open. When the latch is released, Fig. 9, the coil spring 64 draws the jaw 6 toward the jaw 5 to clamp the lining therebetween.

With the upper and lining gaged and clamped, as illustrated in Fig. 9, the machine is started and the mechanism for actuating the series of gripper bars G causes the grippers to draw the upper over the last, whereupon the wipers W, of which only one has been shown, advance to engage and wipe the overworked edges of the stock inwardly and downwardly upon the last bottom. The carriers'for the wipers are then advanced and, after engagement with=the upper, may actuate the latches 88 to open the gripping jaws 4 and 5 and release the upper U, the movement of the jaw 5 to open position automatically returning the jaw 6 to its open position in which it is again latched by the thumb piece 6 thus releasing the lining L.

When the wipers 1V reach position for inserting the tacks,'and with them, the tackdriving blocks B, which may be carried by the carriers for the wipers and are thus positioned simultaneously therewith, they pause, and the tack driving hammers or bars H descend to set a single row of tacks 2? simultaneously through the lining and the upper, whereby to temporarily attach the upper and lining to the last. The construction and mechanism for advancing and retracting the grippers, wipers and tack driving bars may be as in the usual pulling-over machine. a

It will thus be seen that by my invention, the toe cap of a turn shoe may be accurately gaged before tacking, that only one tacking operation is necessary, that fewer tacks are a lining therebetween,

driven, and that all tacks are plainly exposed for the stitcher to observe and avoid when the shoe comes to him and for the tack-puller to observe and draw when the shoe comes to him. My invention therefore not only avoids mismating and the liability of the stitcher breaking the needle of his machine upon concealed tacks, and the tack puller failing to draw these concealed tacks, but effects a substantial saving in time and labor in pulling-over the upper by reason of the reduction of the number of tacking operations from two to one and in tacks by the reduction of the number of tacks actually required to be driven.

Various modifications in the form and operation of my invention may obviously be made, all without departing from the spirit of the invention if within the limits of the appended claims.

IVhat I therefore claim and desire to secure by Letters Patent is:
